Fisheries and Oceans Canada’s (DFO) Coastal Environmental Baseline Program supports the collection of ecological information on the current state of key coastal ecosystems across Canada. This initiative aims to acquire environmental baseline data (physical, chemical and biological) contributing...

Fisheries and Oceans Canada (DFO) conducts an annual multidisciplinary scientific survey with a bottom trawl in the Estuary and the northern Gulf of St. Lawrence since 1978. Over the years this survey has been conducted on four vessels: the MV Gadus Atlantica (1978-1994), the MV Lady Hammond...

In place since 1994 in eastern Canada, the sentinel fisheries program is the result of a collaboration between Fisheries and Oceans Canada (DFO) and commercial fishermen. Under this program, contracts are awarded by tender to fishermen to carry out fishing activities according to scientific...

Ocean physical conditions in the Maritimes Region in 2019 were characterized by cooler surface temperatures, continued warmer bottom temperatures and weaker stratification compared to recent years. Deep nutrient inventories were lower than normal over most of the region, with the exception of the...

Catch, effort, location (latitude and longitude), and associated biological data from groundfish multi-species longline surveys in the northern portion of the inlets and protected waters east of Vancouver Island, British Columbia. Introduction The Inside North Hard Bottom Longline (HBLL)...

Zooplankton and ichthyoplankton data are archived in the Institute of Ocean Sciences (IOS) Zooplankton Database. The data available spans from 1980 to 2018 and is an extraction of vertical net hauls as biomass by major taxa collected during surveys conducted in the oceanic and coastal waters of...

Catch, effort, location (latitude, longitude), and associated biological data from groundfish multi-species longline surveys in British Columbia. Introduction This is a set of long-term and coordinated surveys that together cover most of the nearshore, hard-bottom habitat of coastal British...

Aquatic invasive species pose economic and ecological threats to Canada's coastal waters. In response, Fisheries and Oceans Canada (DFO) has established monitoring programs to detect and track the spread of aquatic invasive species, including European Green Crab, in Canadian waters. Fukui traps...

The European Green Crab (EGC) is a high-risk global invader that can devastate coastal marine ecosystems by displacing native species, degrading and disturbing native habitats (including eelgrass), and altering food webs. EGC has recently been detected in the Canadian portion of the Salish Sea....

Catch, effort, location (latitude and longitude), and associated biological data from groundfish multi-species longline surveys on the northern British Columbia coast, excluding the inlets and protected waters east of Vancouver Island. Introduction The Outside North Hard Bottom Longline...

Zooplankton samples were collected at Ocean Station "P" (50.0000, -145.0000) from 1956 to 1980, and were analyzed to various levels of taxonomic resolution over the years. Although summaries of these data have been previously published ((LeBrasseur 1965) and (Fulton 1978, 1983)) the detailed...

Striped Bass critical habitat (St. Lawrence estuary population) defined by the analysis of available knowledge in 2011 and a scientific advice. Purpose The status of the Striped Bass population of the St. Lawrence Estuary is in constant evolution. It went from indigenous population until the...

This record contains a comprehensive synthesis of previously published highly branched isoprenoid (HBI) results, providing a quantitative spatial and temporal assessment of carbon partitioning within the Arctic marine ecosystem and validating estimates of sea-ice particulate organic carbon (iPOC)...

Considered the "king" of sea lions, the Steller sea lion (Eumetopias jubatus) is the biggest of all sea lions and enjoys a lifespan of up to thirty years. In Canada, the Steller can be spotted along the rocky coast of British Columbia. This hefty mammal usually travels alone or in a small group,...
